How to switch TabbedPage on Login

[chimditruvn]

Hi guys. I have:

MainView.xaml

<TabbedPage> <views:Page1 Title="Page1" IconImageSource="homeicon" BackgroundColor="#fff"/> <views:Page2 Title="Page2" IconImageSource="order" BackgroundColor="#fff"/> <views:Page3 Title="Page3" IconImageSource="ads" BackgroundColor="#fff"/> <views:Page4 Title="Page4" IconImageSource="usericon" BackgroundColor="#fff"/> </TabbedPage>
--> picture 1

I have login page (outside TabbedPage), I write ApiService for it. I login ok, after login I want to redirect the page to Page4 (located inside TabbedPage)

if (response.IsSuccessStatusCode) { var responseBody = await response.Content.ReadAsStringAsync(); App.Current.MainPage = new Page4(); }

I redirect to the Page4 in the TabbedPage. ---> Ok, but it lost the tabs below (picture 2).
Can anyone give me a clear way to solve the problem? Thank you
